In Lisp, you don’t just write your program down toward the language, you also build the language up toward your program. As you’re writing a program you may think “I wish Lisp had such-and-such an operator.” So you go and write it.

Over the past month, I started rebuilding the Raspberry Pi Dramble project using Kubernetes instead of installing and configuring the LEMP stack directly on nodes via Ansible (track GitHub issues here).

tl;dr: when moving more than 500 containers to k8s we ran into some problems. Scroll and read the big titles below to see what they were and how we solved them. MEE6 has been growing fast, going from 0 to 25M users in about 18 months with the CEO also serving as the sole developer.

This is the first in a series of blog posts in which we outline our experience with React Native and what is next for mobile at Airbnb. When Airbnb launched 10 years ago, smartphones were in their infancy.

We organize the project by the Agile methodology. We have begun by a “kickoff” page under confluence to initiate the project. A formal kick-off meeting must be set up if at least one of the following conditions is met:

Making it possible that “everyone can contribute” is our mission, and any development that brings us closer to it is great news! That’s why we’re happy to tell you that open source content management system Netlify CMS is launching support for GitLab as a back end today.

So, a few days ago I saw tweet Kayle Gill about building static e-commerce site using GatsbyJs. That time I was in process of building an e-commerce website for my wife using NextJs (which is also awesome!). Instead of building the site with NextJs I tried GatsbyJs.

Welcome to another entry in the Getting Started series! In this post we’ll talk about how to use Red Hat Satellite 6 as an inventory source within Ansible Tower. A common scenario we see is the use of Satellite 6.

The Cloud Native Computing Foundation (CNCF) voted to move Helm from underneath the wing of Kubernetes and into its own incubation-level hosted project. The move is set to allow Helm to prosper on its own as well as allow Kubernetes to maintain a focus on its evolution.

Progressive decoupling and ES6 support on Drupal 8 are definitely gaining some momentum. After having tested several methods to make use of React within Drupal, I had a look a the React Comments module. What I like about the approach that the maintainers took, is that React is:

A very common scenario is when you are hosting your own database, but doing so outside the cluster, for example on a Google Compute Engine instance. This is very common if you run some services inside Kubernetes and some outside, or need more customization or control than Kubernetes allows.

I focus on helping teams and organizations reduce technical debt. This means a lot of work in legacy applications. But once technical debt has been reduced, it’s important to think about how we will avoid creating too much new technical debt in the future.

Package management, dependency management, configuration management, and who knows how many other forms of management exist when it comes to computing systems. We have managers for managers for operators of applications.

When it comes to APIs, change isn’t popular. While software developers are used to iterating quickly and often, API developers lose that flexibility as soon as even one user starts consuming their interface. Many of us are familiar with how the Unix operating system evolved.

One of the technologies that has caught my eye in recent days is GraphQL. Additionally, I’ve been doing a lot of work with Go and gRPC at work, so I was curious if there was a way that these technologies could play nicely with one another. Then, it hit me.

Today, we’re excited to announce Pyre, a static type checker for Python. Pyre is designed to help improve the quality and development speed in large Python codebases by flagging type errors interactively in your favorite editor.

The classic case discussed for branch by abstraction is the changing of one persistence technology for another. In the original article⇩ for this, it was swapping out Java’s ‘Hibernate’ technology for ‘iBatis’ (now MyBatis). That was hypothetical for the blog entry.

With traditional containers, the kernel imposes some limits on the resources the application can access. These limits are implemented through the use of Linux cgroups and namespaces, but not all resources can be controlled via these mechanisms.
